radiobutton组的必需字段验证器不是radiobutton列表 [英] Required field validator for radiobutton group not radiobutton list

问题描述

我需要为单选按钮组中选择的至少一个单选按钮提供必需的字段验证器。



仅供参考 - 我不是在寻找单选按钮列表所需的现场验证器。



谢谢，

I need to have required field validator for at least one radio button selected in a radio button group.

FYI - I am not looking for required field validator for radio button list.

Thanks,

推荐答案

为什么需要单选按钮的验证器控件。只需在组中选中/选中一个单选按钮即可。如果你不想这样做，那么为什么不写一个简单的javascript函数来验证单选按钮的状态。

Why do you need a validator control for radio button. Just make one radio button selected/checked in the group by default. If you don't want to do that than why not just write a simple javascript function to validate the radio buttons' state.

<asp:RadioButtonList ID="RadioButtonList1" runat="server">
        </asp:RadioButtonList>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="RadioButtonList1" runat="server" ErrorMessage="Select Item !"></asp:RequiredFieldValidator>
